757 | # TCL/EXPECT WART ALERT |
758 | # Expect does something very strange when it receives a single braced | |
759 | # argument. It splits it along word separators and performs substitutions. | |
760 | # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is | |
761 | # evaluated as "\[ab\]". But that's not how TCL normally works; inside a | |
762 | # double-quoted list item, "\[ab\]" is just a long way of representing | |
763 | # "[ab]", because the backslashes will be removed by lindex. | |
764 | ||
765 | # Unfortunately, there appears to be no easy way to duplicate the splitting | |
766 | # that expect will do from within TCL. And many places make use of the | |
767 | # "\[0-9\]" construct, so we need to support that; and some places make use | |
768 | # of the "[func]" construct, so we need to support that too. In order to | |
769 | # get this right we have to substitute quoted list elements differently | |
770 | # from braced list elements. | |
771 | ||
772 | # We do this roughly the same way that Expect does it. We have to use two | |
773 | # lists, because if we leave unquoted newlines in the argument to uplevel | |
774 | # they'll be treated as command separators, and if we escape newlines | |
775 | # we mangle newlines inside of command blocks. This assumes that the | |

3442 | # parameter and most options are passed directly to it. | |
3443 | # | |
3444 | # The type can be one of the following: | |
3445 | # | |
3446 | # - object: Compile into an object file. | |
3447 | # - executable: Compile and link into an executable. | |
3448 | # - preprocess: Preprocess the source files. | |
3449 | # - assembly: Generate assembly listing. | |
3450 | # | |
3451 | # The following options are understood and processed by gdb_compile: | |
3452 | # | |
3453 | # - shlib=so_path: Add SO_PATH to the sources, and enable some target-specific | |
3454 | # quirks to be able to use shared libraries. | |
3455 | # - shlib_load: Link with appropriate libraries to allow the test to | |
3456 | # dynamically load libraries at runtime. For example, on Linux, this adds | |
3457 | # -ldl so that the test can use dlopen. | |
3458 | # - nowarnings: Inhibit all compiler warnings. | |
3459 | # | |
3460 | # And here are some of the not too obscure options understood by DejaGnu that | |
3461 | # influence the compilation: | |
3462 | # | |
3463 | # - additional_flags=flag: Add FLAG to the compiler flags. | |
3464 | # - libs=library: Add LIBRARY to the libraries passed to the linker. The | |
3465 | # argument can be a file, in which case it's added to the sources, or a | |
3466 | # linker flag. | |
3467 | # - ldflags=flag: Add FLAG to the linker flags. | |
3468 | # - incdir=path: Add PATH to the searched include directories. | |
3469 | # - libdir=path: Add PATH to the linker searched directories. | |
3470 | # - ada, c++, f77: Compile the file as Ada, C++ or Fortran. | |
3471 | # - debug: Build with debug information. | |
3472 | # - optimize: Build with optimization. | |
